Influence of knit and miss stitches on air and water vapour permeability of flat knitted rib fabrics

The double jersey flat knitted rib fabrics were produced and used for the investigation. during flat knitting operation,the percentage contribution of knit (k) and miss (m) stitches in the fabric structure has varied to study the air and water vapour permeability properties of the fabric. the variation in the fabric is in three levels such as 100k: 0m,87.5k: 12.5m and 83k: 17m. one way analysis of variance is conducted to test the significance of test results. in order to confirm the significance of result,tukey's least significant test also used for this study. based on the tests conducted in this study,the contribution of knit and miss stitches in the fabric influences the permeability properties of knit fabric significantly.
